I've recently moved into a new apartment complex which consists of townhouse style units side by side to each other. When signing the lease with the real estate agent, the question was brought up about the allowance of pets. I told her that I have a cat and she recommended after moving in and getting settled to contact the landlord and formally request permission to be able to house a cat. I have since discovered that in my complex there at least three other tenants with dogs, including each unit on the sides of mine. Upon requesting formal permission from the landlord, he said he will not grant permission to have a cat. When questioned why the other tenants are allowed to have dogs, including the ones on each side of my unit, he said that he was trying to get the facility away from being pet friendly. Is this justifiable on his behalf? Is there any kind of discrimination going on? Any help or advice would be greatly appreciated.
